You can have dedicated controllers for the motors that limit their max torque.

That's not enough. When a robot link is in motion and hits an object, the change in momentum creates an impulse over the duration of deceleration. The faster the robot moves, the faster it has to decelerate, the higher the instantaneous braking force at the impact point.
